FIGURE'lS isa section through an adapter shown in phantom in FIGURE 13/enlarged section Oil line vrn vtn tongues 68 slidably fitted between theflanges 44 of the associated post 40. Each plate 66 rigidly securestogether the associated end portions of the members 56 and positionsthemembers 56 with their webs 58 disposed in planes which convergeupwardly, as shown. Each plate is provided with a hole 72, and projectedthrough a lock washer 74 and the hole 72 is a screw 76 threaded intoanut 78. The nut is of a depth slightly less than the clear distancebetween the inturned portions 48 of the flanges I k 44, and diagonallydisposed corners of the nut are yarn packages of a different. size andnumber at another rounded, as at 79. One face of the nut is providedwith laterally spaced parallel grooves 81 which receives marginal areasof the inturned portions 48 of the flanges-44. The bottom of each groove81 is provided with a series of transversely extending teeth 84 whichfirmly engage the opposed edge of the associated inturned portion 48.

Each member 56 mounts a plurality of pins 80, each of which has a.threaded portion 82 extending from a flange 85 at the base thereof andbetween the flanges 60, of the member 56. The portion 82 is threadedinto a nut 86 non-turnably captured between the flanges of the member56. The portions 64 of the flanges 60 overlie the nut 86 and secure thesame against being pulled out from between the flanges 60. It will benoted that the pins are inclined at an angle of approximately fifteendegrees relative to the horizontal. The body of the pin is tubular andtapered from a large diameter at the base of the pin to a smallerdiameter at the opposite extremity thereof. Fitted over the main body ofthe pin, next to the flange 85, is a collar 87. The pin 80 in itsentirety, including the nut 86, preferably is made of nylon.

On each side of the truck is a tubular handle bar 88 which isrectangular in shape. Referring to FIGURES 4 to 6, each bar 88 issecured to the associated post 40 by a pair of clips 90. Each clip has asemicircular main Referring to the drawings, a pirn'truck constructedbody part extending about the tube and terminating at one end in aportion 92 extending tangentially therefrom. At the opposite end is anear 94 disposed at right angles to the portion 92. The portion 92 isrecessed on opposite sides, as at 96, to provide shoulders 98. Therecesses 96 accommodate the flanges 44 of the post 40 and the shoulders98 are opposed respectively to the inturned portions 48 of the flanges44. The clip is adjustably secured to the post 40 by a bolt 100extending through the car 94 and threaded into a nut 78.

In the use of the truck, pirns or bobbins of yarn, designated P, arefitted over the pins 80, thus affording a bank of pirns or bobbins ofyarn P on each side of the framework 38. Each pin is adjustably fixed inposition. To shift the pin horizontally, it is turned about its axis ina 3 direction to loosen its grip on the channel member 56. Then the pin80 and nut 86 are shifted as a unit to the desired position, whereuponthe pin 80 is turned about its 'axis in the opposite direction toretighten the connection. Each assembly 54 is adjustably fixed inposition. To shift the assembly 54 vertically, the screws 76 are turnedout sufficiently to loosen the grip of the nuts 78 on the posts 40. Thenthe entire assembly 54 is raised or lowered as desired, whereupon thescrews 76 are turned in again to retighten the connections. It will benoted that one or more of the assemblies 54 may be conveniently removedas a unit from the framework 38 or added thereto to accommodatedifferent sizes of yarn packages and different numbers thereof. Forexample, as illustrated, nine assemblies 54 are employed. Each assemblymounts ten yarn packages in all. This arrangement accommodates a totalof ninety yarn packages. However, if desired, nine assemblies 54 may beemployed, with each assembly mounting eight comparatively large yarnpackages. Thus a total of seventy-two comparatively large yarn packagesmay be accommodated. In addition, the arrangement of pins 80 on one sideof the framework may be different than that on the other side to suitrequirements. Furthermore, pins that are in use may be removed readilyand pins different in size and/or shape may be substituted therefor tocarry yarn packaged differently.

For example, referring particularly to FIGURE 10, pins 80 may be removedand replaced by pins 102, which are similar in every respect to pins 80,except that the collar 87 is omitted. A package of yarn (not shown) maybe mounted directly upon the pin 102. On the other hand, the cylindricalcore 103 of a yarn package P may be fitted over an adapter 104, which inturn is mounted upon the pin. The adapter is provided with a centrallydisposed annulus 106 at the outer end thereof fitted snugly over thetapered body of the pin. Extending radially outwardly from the annulus106 are a pair of diametrically opposite wings 108 and a pair ofdiametrically opposite wings 109 equally spaced about the annulus andextending therefrom toward the base of the pin. Intermediate theopposite ends of the adapter are a pair of axially spaced webs 110 and112 interconnecting the wings 108 and 109. The pin extends freelythrough the webs. The portions of the wings 109 extending rearwardlyfrom the web 112 about the flange 85, while the portions of the wings108 extending rearwardly from the web 112 are shaped, as at 114, to snapover the flange 85 of the pin. The adapter 104 preferably is made ofnylon.

Referring particularly to FIGURE 11, the adapter 104 may be replaced byan adapter 116 capable of mounting the package P The adapter 116 isprovided with an axially extending tapered tubular sleeve 118 which fitssnugly over the tapered body of the pin 102. Equally spaced about thesleeve 118 and extending longitudinally thereof are a pair ofdiametrically opposite wings 120 and a pair of diametrically oppositewings 121 equally spaced about the sleeve 118. Intermediate the oppositeends of the adapter are a pair of axially spaced webs 122 and 124interconnecting the sleeve 118 and the wings 120. The portions of thewings 121 extending rearwardly from the web 124 are adapted to abut theflange 85, while the portions of the wings 120 extending rearwardly fromthe web 124 are' adapted, as at 126, to snap over the flange 85 of thepin 102. The adapter 116 preferably is made of nylon.

Referring particularly to FIGURE 12, the pin 80 may be removed andreplaced by a pin 128. Threaded over the base end of the pin is a nut130. Underlying the nut is a flat washer 132 and underlying the flatwasher is a cylindrical spacer 134 preferably made of nylon. The washeris seated upon the flanges 60 of the associated member 56, and thespacer extends freely between said flanges. The end of the pin extendingbeyond the spacer is threaded into a nut 78. Extending about the washeris the axially extending cylindrical portion of a flange 136. The pinmounts a package of yarn P wound on a spool 138 fitted over the pin. Thespool is provided at one end with a base flange 140 seated against theflange 136 and at the opposite end with a flange 142.

Referring to FIGURES 13 to 15, the pin 80 maybe removed and replaced bya pin 144 provided with a cylindrical main body 146. Equally spacedabout the -cylindrical body and extending longitudinally thereof arefour wings 148 terminating at the base of the pin in a web 150.Extending axially from the web 150 is an externally threaded tubularportion 151 by means of which the pin may be adjustably secured to themember 56, with its web 150 seated against the flanges thereof. Thewings 148 are stepped to provide shoulders 152 of minor radial depth,154 and 156 of intermediate radial depth and 158 of maximum radialdepth. The pin 144 mounts a package of yarn P wound on a spool 160fitted over the pin and provided with an insert 162 fitted over theouter end portion of the pin. The inner end portion of the spool 'fitsover the shoulders 158.

An adapter 164 having a'centrally apertured wall 166, an axiallyextending inner flange 168 and an axially extending outer flange 170 maybe fitted over the end of the pin 144. The outside diameter of theadapter 164 corresponds to the distance between oppositely facingshoulders 154 so that the cylindrical spool of a yarn package (notshown) may be fitted over said shoulders and adapter. The pin 144 andthe adapter 164 preferably are made of nylon.

In mounting an assembly 54 on the posts 40, the assembly is lowered overthe posts 40 to the desired position thereof. The nuts 78 are then heldwith their grooves 81 extending horizontally, and then inserted betweenthe flanges 44 of the posts. After positioning the nuts with theirthreaded openings in registry with the openings 72 in the plates 66, thebolts 76 are projected through the lock washers 74 and the openings 72and threaded into the nuts 78. As a screw 76 is turned into the nut 78,the nut turns till the corners that are not rounded engage the flanges44 of the posts. When this occurs, the grooves 81 are in registry withthe edges of the inturned portions 48 of the flanges 44. When the screw76 is threaded fully into the nut 78, the teeth 84 at the bottom of thegrooves 81 are firmly engaged with the edges of the inturned portions 48of the flanges 44. The vertical position of the assembly 54 may beadjusted by loosening the screws 76, moving the assembly as a unit tothe desired position thereof and then retightening the screw 76. It willbe noted that above the base frame 10, the posts are tied togethersolely by the assemblies 54. Therefore, the assemblies 54 may beassembled with the posts 40 by lowering them thereonto each as a unit,and may be removed from the posts 40 by raising them each as a unit. Inother words, it is not necessary to disassemble a frame 54 in order toassemble it with or remove it from the posts 40.

In addition, it will be noted that the members 56 are open ended channelmembers. Thus the number of pins mounted thereon may be readilyvaried'by slipping the pins on and off endwise.

It is unnecessary to provide the specific channel iron construction forthe adjustable pirn rails 56' for it will be apparent to those skilledin the art that manydiiferent shapes may be substituted withoutdeparting from the spirit of this invention. In addition, equivalentelements may be substituted for those specifically shown in the drawingsand described herein, parts may be reversed, and certain features of theinvention may be used independently of other features, all withoutdeparting from the scope of the invention as defined in the appendedclaims. v
